WARNING-SIGNAL.

Specification of Letters Patent. Patented Sept. 16, 1919.

Application filed July 27, 1918. Serial No. 247,004.

To all whom it may concern:

Be it known that I, JOHN EDGAR MYnRs, a citizen of the United States of America,

. tion for receiving light rays projected from the lamps of approaching automobiles; or other vehicles and designed to color and reflect rays impinging thereon to visually indicate to the drivers of such vehicles the presence of danger at or near such point.

A further object of the invention is to provide a lightless color signal whereby drivers of lighted vehicles may be visually warned of the presence of a danger point in a roadway with practically the same effect as if a lighted lamp of the same color were employed at such point. A

" In describing the invention in detail, reference is herein had to the accompanying drawings, in whic'h v Figure 1 is a front elevation of the colored glasslight reflector which constitutes an essential feature of the invention;

Fig. 2 is a partial vertical sectional view of the invention; and- Fig. 3 is a reduced front elevation of the invention mounted upon a post.

which Referring to said drawings, in like designating characters distinguish like .partsthroughout the several views- A indicates generally a hollow circular blown glass reflector having a concave front or reflecting face 1 and having a convex back 2 disposed rearward of said face, as shown in Fig. 2. The glass of which said reflector is composed may be of any preferred color, but is preferably ruby red to indicate danger, or green to indicate that caution should be observed. The interior or rear surface of the face 1 of the reflector is coated with quicksilver which is introduced through the neck 3 that is integrally carried by the back 2 in a central position, said neck being retained following the to the drivers of such cars.

blowing operation. After the introduction of the quicksilver or other ooati'ng employed for rendering the glass effective as a reflector, the neck 3 is hermetically sealed to prevent access of moisture which would otherwise cause the coating to deteriorate rapidly and thus destroy the efficiency of the device as a reflector.

Owing to the more or less fragile character of the reflector, the same is preferably mounted within an inclosing frame or casing 4 whereby it is shielded against injury, such casing being provided with a clear glass front 5 through which light rays may pass unobstructedly. Said casing may be of any preferred form adapted for mounts ing upon a post 6 or other convenient support, the casing herein shown for illustrative purposes being of plain box-like form and having a socketed member 7 attached interiorly to the back ther of, said mem ber being adapted to have tl e neck 3 of the reflector seat snugly in the socket thereof for supporting said reflector.

The invention is designed for mounting in suitable position at or adjacent to points of danger in a roadway, as at dangerous turns, crossin s, and the like, where the face of the re ector will, receive rays of light projected from the lamps of approaching cars and directly return such rays by reflection and in the color of the glass as a warning Concentrated beams or shafts of light of great brilliance and of the color of the glass are returned by the face of the reflector, the appearance and effect being substantially the same as that of a lighted slgnal lamp with a colored lens located at. the same point.

The invention is also adapted for use as a warning signal onhorse-drawn or other road vehicles and obviously may take the place of the usual tail lamp on automobiles.

As is apparent, various advantages are possessed by the invention described, among quicksilver and hermetically sealed, said reflector having a concave reflecting surface.

2. A signal of the character described, comprising a hollow reflector of colored glass having a concave reflecting surface, said reflector being silvered interiorly and being closed to prevent access of moisture to its interior. I

3. A signal of the character described, comprising a hollow bloWn reflector of colored glass having a concave reflecting surface, saidreflector being silvered interiorly and having posed centrally of the back thereof, and a casing inclosing said reflector, said casing having a transparent glass'face.

4:. A signal of the character described,

a hermetically sealed neck oliscomprising a hollow blown reflector of colored glass having a concave reflecting surface, said reflector being silvered interiorly and having a hermetically sealed neck disposed centrally of the back thereof, and a casing for said reflector, said casing having a portion in which the neck of said reflector is seated for supporting the latter, and having a transparent glass face in front of said reflecting surface.

In testimony whereof I affix my signature in presence of two subscribingwitnesses.

JOHN EDGAR MYERS.
